CAR CONSTRUCTION.

Application filed January 14,1926. Serial No. 81,193. I

My invention relates to car constructions,

ger oi opening of the joints between the edges of the car ends and theadjacent walls of the car, and wherein the .car end is joined morefirmly to the adjacent walls than in structures heretofore employed.

Another object of my invention is to provide car end structure whereinimproved means are provided for preventing passage of air or moisturepast the edges of the car end to the interior of the car.

Another object of my invention is to provide a car end so mounted as tobe movable out of closed position, ther'eby serving as a door forproviding access to the interior of the car. I

Another object of my invention is to provide a door structure having animproved form of locking mechanism, and onewherem provision is madefor'effecting a tight clo sure as operating door frame structure.

One form which my invention may take is shown in the accompanyingdrawing, wherein Fig. 1 is an end elevational v ew of a car with myinvention applied thereto; Fig. 2 is a vertical sectional view on thehne2-2 of Fig. 1; Fig. 3 is an enlarged elevational view of the lockingmechanism; Fig. 4 is a section on the line 4-4 of Fig. 3, and 5 is asection on the line 5-5 of Fig. 1, showing the corner structure of thecar at the hinge side of the door.

For convenience of description I have shown my invention as applied to arailway car end wherein such end is hingedly mounted to serve as a doorto provide access to the interior of the car, but the invention is notlimited to car ends nor to car ends that serve also as doors.

The door is composed of panels 11 and 12 riveted together at theiradjacent edges and having marginal angles 13, 14, 15 and 16 rivetedthereto.

The door is shown as supported against a framework composed of verticalangles 17 and 18 (Figs. 4 and 5) that are secured to the posts 19 and20, respectively, a portion of the side walls of the car. A top framemember is also provided consisting of plates '21 and 22 (Fig.2) that areconnected between the edges of the door and cov which form to the sidewall structures of the car in any suitable manner. A bottom door framestructure consists of a plate 23 that is secured to the floor 24 of thecar and the end sill or platform 25.

Four hinges 26 are secured to the door and to an angle iron 27 thatextends vertically the full height of the door and is secured to theangle .18. A plate 28 is secured to the angle 14, such plate beingprovided with an outturned edge that cooperates with the inturned edgeof the bar 27., thereby creating an overlapping structure which tends toprevent access otmoi-sture or entry of air past the edge of the door. 7

Three latch bars 30 (Figs. 3 and 4) are provided at the right hand edgeof the door to hold the same closed. These latch bars are each pivotallymounted upon a pin 31 that is supported in bearings 32. which arefastened to the side wall structure of the car. The bars 30 are held inlatched position by means of. locking pins 33 that extend throughopenings in the flanges 34 of keepers 35 that are secured to the face ofthe car end. The ripper ends of the locking pins 33 are bent over :33 sothat the pin may be turned to the position indicated dotted lines inFig. 3, and the end33 caused to rest upon a ledge 35 to thereby hold thelocking pin 33 in raised position and permit the latch bar 30 to beswung outward.

The bearing brackets 32 are each connected to the forward end of aspring plate 36 (Fig. 4 by means of rivets 37., the spring plates inturn being riveted to the vertical angles 17 of the side wall. Averticallyentending angle bar :33 is disposed between the spring plate3.6 and the bearing bracket 32 with its flange turned inwardly tooverlap the outwardly extending flange of a vertically disposed angle 39that is secured tothe door frame angle 13, thereby making .a tight jointbetween the edge of the door and the adjacent side of the car. The anglebars 33 and 39, when overlapped as shown in Fig. 4, serve as stopmembers tor holding the door closed. I i

A guide member 41 is provided for each latch bar 30, such guide memberbeing rigidly secured to the angles 17 and 13.. .In order to open thedoor, the pin 33 is raised to the position shown by dotted lines in Fig.3 and the latch bar '30 swung outward about its pivot 31 until itscamusurface 30 is connected to three hinges 44 (Fig. 1)

are secured to the end plate 21. The outer 39 is brought into engagementwith either the camming surface 30 of the latch bar or with the cammingsurface 32 of the support ng bracket 32, to force the angle 38 outwardand a permit the angle 39 to assume the position shown in Fig. 4, atwhich time the lever30 can again be locked. 1 i

A sealing joint is provided at the top of the car by means of an angle43 (Fig. 2) thap1 is t at edge of the angle 43 overlaps the door frameangle 16, as shown more clearly in Fig. 2, and

its inner end is turned upwardly between the plates 21 and 22 thatextend across the end of the car. The angle 43 is connected totwo links45, so that when it is desired to open the door, pins 46 by which thelinks are sup ported from the bracket 46 are removed from the bracketsand the links lifted until their openings 47 are in position to beengaged by the pins 46 and the links then supported by bracket 46 inraised position, thus holding the angle 43 out of the path of the angle16. When the outer edge of the angle 43 is swung vertically about itspivots 44, the inner upturned flange of the angle moves through an arcand is thus guided into and out of its seat between the plates 21 and22.

At its bottom edge, the car end is provided with two pairs of ears 50(Fig.2) that are perforated for the receptionof locking pins 51 whichserve to retain holding levers 52 in locked position. The levers 52 arepivotally connected to an angle 53 that extends across the lower end ofthe car door and has its inner edge 53 interlocked with the edge 23 ofthe plate 23. The lever 52 is provided with a nose portion 52 thatengages the bot tom angle 15 of the door, when in closed position,thereby holding the outer end of the angle 53 in elevated position. Theoverlapping edges 23 and 53 serve as a seal. WVhen the latch 52 is swungoutwardly, the outer edge of the angle 53 drops clear of the angle 15,to permit opening of the door. A guide plate 54'is secured to the innerface of the door to bring it to proper vertical position when the dooris being closed.

From the foregoing it will be seen that I provide a door that may bereadily opened and wherein the edges are efiectively sealed.

The door possesses a still further advantage in that pressure of ladingagainst the inner The door can then be moved to face thereof will notcause spreading of the joints between the vertical edges of the door andthe car sides, by reason of the fact that the hinges and the latchescooperate as tie members to maintain the sides and the door of itsplane, of an angle member secured to the door atone edge thereof, aspring plate secured to thedoor frame, and a plate car ried by saidspring plate and normally overlapping the said angle member, the saidangle member and the second-named plate being substantially co-extensivein length with the vertical edge of the door.

2. The combination with a door. frame and 'a door movable in a directiontransversely of its plane, of a plate secured to the door at one edgethereof, a spring plate secured to the door frame, a: sealing platecarried by said spring plate, the sealing plate normally overlapping thefirst-named plate, and acainming member mounted in position to flex thespring plate outwardly to permit the other plates to clear one another,the said angle member and the sealing plate be ing substantiallyco-extensive in length with the vertical edge of the-door.

3. The combination with a door frame and a doormovable transverselythereof, of an angle at one side of the door frame and substantiallyco-extensive inlength with the ad jacent edge of the door, a platesecured to the door in position to abut against an inner surface of thesaid angle when the door is closed, a spring plate secured to the doorframe and to the angle and arranged to yieldabl hold said angle at aninner position am in overlapping relation to theplate when the door isclosed,and means for holdlll) ing said angle against movement relativetoi the said plate and for flexing said spring plate to move the angle outof said overlapping relation. 1

4. The combination with a door frame and a door, of an angle disposedalong one ed e of said door, a second angle carried by said frame, andmeans for yieldably supporting one of said angles inposition to overlapthe other angle, the said angles being substantially co-extensive inlength with said edge of the door.

5. The combination with a door frame and a door, of an angle disposedalong one edge of said door, a second angle carried by said frame, meansfor yieldably supporting one of said angles in position to overlap theother angle, and means associated with one of said angles for varyingthe relative positions of the angles, the said angles beingsubstantially co-extensive in length with said edge of the door.

6. The combination with a door frame and a door, of an angle disposedalong one edge of said door, a second angle carried by said frame, andmeans for movably supporting one of said angles in position to overlapthe other angle, the said angles being substantially co-extensive inlength with said edge of the door.
